NRCS Briefing on Orthoimagery for Hawaii and the Pacific Basin

2.
Why USDA for Orthoimagery ?<br /><ul><li>USDA supports GIS data acquisition and development in all geographical areas of the United States including Hawaii, Pacific Basin, Alaska, Puerto Rico and the US Virgin Islands.

3.
USDA supports Special Emphasis Programs such as the Asian American and Pacific Islanders programs.

19.
USDA-NRCS/FSA collected Orthoimagery for the Hawaii Islands in 1997-2002. When the contracts finished in 2002, 70% of the Hawaiian Islands was successfully collected at a cost of +1.2 Million.<br />

20.
Hawaiian Islands<br />December 2009<br /><ul><li> As a result of the Emerge Aerial acquisition collection, Satellite Technology was considered for the subsequence collection.

21.
USDA- NRCS started using Satellite acquisition in 2005 with primary DigitalGlobe. Complete statewide acquisition was finished in 2009.

22.
- Oahuis collected by DHS/NGA/USGS as part of the Urban 133 areas project.

24.
Complete coverage was accomplished in 2009 with the deliveries of DOQQ’s for Hawaii Island at a cost of ~ $ 600,000 including Enterprise Premium upgrades.</li></li></ul><li>Original Source QB Imagery (Top) and USDA-NRCS Tone Balanced Imagery (Bottom).<br />USDA has made available both original GeoTIFF files (Top) and processed imagery files bottom to Federal and State Agencies.<br />

31.
WorldView-2 Traditional Spectral Bands<br />Blue (0.45 - 0.51 µm)<br />MS4 is designed for water body penetration, making it useful for coastal water mapping. Also, useful for soil/vegetation discrimination, forest type mapping and cultural feature identification. <br />Green (0.51 -0.58 µm)<br />MS3 is useful for measuring green reflectance of vegetation. It can also be used for cultural feature identification.<br />Red (0.63 -0.69 µm)<br />MS2 is sensitive to chlorophyll absorption region. It is useful for vegetation analysis and can even be used to differentiate plant types. It is also useful for cultural feature identification.<br />Near Infrared (NIR1) (0.77 -0.895 µm)<br />This band is useful for determining vegetation types, vigor and biomass survey, delineating water bodies, and for soil moisture discrimination.<br />

41.
Plant Species Identification<br />Wild plant populations are much more complex than organized farmlands, consisting of multiple species<br />Some are invasive pests, while others have potential value such as biofuels<br />With the increased spectral bands of WorldView-2, plant species can be differentiated from each other and accurately mapped<br />

69.
World-View-2 Eight Band Research Questions?<br />Here is the basic set of questions that we are trying to have researchers address. I’m not sure what stage you are at in your research but hopefully these questions can at least guide you as to what information we are trying to collect.<br /><ul><li>What is the hypothesis you are testing, or the project you are working on?

70.
What are the early results/indications for improvements with WV-2 data?

72.
Can you quantify the improvements in terms of efficiency/speed/productivity/manual intervention?

73.
When will you have quantitative data and can we publish it as a research / case study?

74.
Can you provide us your ground truth so that we can do our own analyses?

75.
Do you have an idea of how this research would be applicable to existing commercial markets or applications?

76.
Have you conducted other studies with traditional 4 band imagery? </li></li></ul><li>DigitalGlobe 8 Band Multi-Spectral <br />Pan Sharpening Testing at USDA-NRCS<br />- In the past USDA has acquired Pan-Sharpen data from Orthoimagery DigitalGlobe. <br />- Cost considerations and the necessity to acquire native MS/Pan data prompted USDA/USGS to not contract for Pan Sharpen Orthoimagery.<br /><ul><li>With the acquisition of DG-WV2, 8 Band Multi-Spectral / Pan Band data, testing is needed to determine best available Pan-Sharpen Techniques.

77.
Pan Sharpening testing has been started in ERDAS 2010, The following methods have been tested as of August, 2010.

92.
<ul><li> USDA-NRCS with the help of the USFS upgraded all USDA acquired DigitalGlobe QB2 Orthoimagery for Hawaii and the Pacific Basin to Enterprise Premium.

93.
USGS and State of Hawaii have agreed that the Enterprise Premium License will meet their agency application requirements.

94.
Allows USDA to post compressed Orthoimagery mosaics of all Hawaii/Pacific Basin QuickBird data to the Public on the USDA Gateway. All users (Federal Civil/Defense, State, Local, Educational, General Public, US Territories/Trusts) except for profit companies have access to these datasets. </li></li></ul><li>DigitalGlobe Enterprise Premium License would allow the following.<br />- Allows USDA to post compressed mosaics of all QuickBird data listed in Appendix A on the “Public” side of the USDA Gateway. All users would have access to these datasets. The USDA Gateway is also the compressed raster data distribution portal for Imagery for the Nation (IFTN).<br />- Allows QuickBird data to be hosted on a Web Map Service (WMS) available to the General Public if the site does not charge a fee for the service. <br />- All Federal/State/Local Government, Universities, Non-Profit Organizations and the General Public would be allowed to use DG Satellite data. <br />

95.
DigitalGlobe Enterprise Premium License exclusions.<br />- DigitalGlobe currently does not offer a “Public Domain” license for QuickBird data. The Enterprise Premium License is the most open license available from DigitalGlobe.<br />- The only exclusion in broad terms of the Enterprise Premium License is that DigitalGlobe QuickBird Imagery data itself could not be re-sold by anyone else (Vendors, Universities etc..). Please refer to Appendix C and D for more information on exclusions to Enterprise Premium. <br />

98.
http://datagateway.nrcs.usda.gov<br />Gateway :<br />- DG Enterprise Premium License will allow compressed mosaics on the Public Side of the Gateway.<br />- Mosaic must be compressed at 20:1<br />- USDA finished re-compressing at Hawaii mosaics and updating metadata.<br />-MrSID mosaics are available on Gateway or Data Discs from Henry Wolter/Tony Kimmet.<br />- Hawaii DG/QB2 mosaics are now posted on the Public Side of the Gateway!<br />

USDA Orthoimagery Acquisitions, Part 1<br />American <br />Samoa<br />NW Hawaiian<br /> Islands<br />Marshall<br />Islands<br />Guam-CNMI<br />Palau<br />Misc.<br />Most Islands/Atolls above are Orthoimagery however some were originally produced as Georeferenced due to a lack of DEM’s before 2007 when SRTM became available<br />Complete list with Image Acquisition dates and License level will be available in July 2010.<br />

104.
USDA Orthoimagery Acquisitions, Part 2<br />Federated States of Micronesia<br />Most Islands/Atolls above are Orthoimagery however some were originally produced as Georeferenced due to a lack of DEM’s before 2007 when SRTM became available<br />Complete list with Image Acquisition dates and License level will be available in July 2010.<br />

105.
American Samoa, Tutuila<br /> Tsunami struck American Samoa on September 30th, 2009. <br />USDA-NRCS provided Orthoimagery used in the Geospatial community for Disaster Response.<br />

106.
American Samoa, Tutuila<br /><ul><li> USDA contracted with DigitalGlobe to provide Tsunami struck American Samoa with a updated Orthoimagery in early October, 2008. 30th,

107.
USDA-NRCS provided Orthoimagery used in the Geospatial community for Disaster Response.

110.
USDA-NRCS Future Satellite Trends…..<br /><ul><li> Increase use of higher resolution, multi-band imagery from sensors such as DigitalGlobe WorldView-2 (DGWV2) will be tested in NRCS. It is possible that DGWV2 eight bands can be used in selective Remote Sensing applications that require more than four bands.

111.
USDA-NRCS will continue to depend on Satellite contracts from USDA-FAS for acquisition of Orthoimagery. </li></li></ul><li>Thank You for your time<br />Above the Clouds on Haleakala Crater NP at Sunset<br />
